Goodman 20201901 Condensate Drain Hose Tube

The 20201901 is a genuine OEM condensate drain hose tube for the Goodman GCH90905DXAA condensing gas furnace. This molded/flexible drain line moves acidic condensate through the furnace's drainage system between the collector box, trap, and inducer/pressure-switch ports. As it ages, the hose can stiffen, split, or accumulate scale and biofilm, restricting flow and triggering pressure-switch lockouts or cabinet leaks. The correct factory-spec tube restores reliable drainage.

Specifications

Part number: 20201901
Type: Flexible/molded condensate drain hose tube
Fits: Goodman GCH90905DXAA and compatible furnaces
Material: Condensate-rated tubing
Application: Furnace condensate drainage routing
Brand: Goodman OEM

OEM vs. Generic

Because this tube may include factory-molded bends and specific end fittings, the OEM Goodman part is the reliable choice — it drops in without adapters and seals correctly. Generic straight tubing rarely matches molded contours, so we strongly recommend the direct-fit OEM 20201901.

Install Difficulty

Easy (2/5). Disconnect the old hose from its fittings, route the new tube along the same path, and reseat clamps. About 15–20 minutes. Confirm there are no kinks or reverse slopes that could hold water.
